  • COLD SINTERING PROCESS OF USING SODIUM BETA ALUMINA
    Publication number: 20220388856
    Abstract: Embodiments relate to a method for fabricating a sintered sodium-ion material. The method involves mixing a parent phase sodium-ion compound with a secondary transient phase to form a powder mixture. The method involves applying pressure and heat above a melting point or boiling point of the secondary transient phase to drive dissolution at particle contacts and subsequent precipitation at newly formed grain boundaries. The method involves generating a sintered sodium-ion material with >90% relative density.
